I make up all my anchor cables out of used snares, with a loop on each end. i make them no less than six feet long.

the important thing is to leave one end with a loop big enough to pass a 330 through.

Put the cable on a spring eye, by passing the cable through the small loop. Now the cable is on the trap.

Now go around whatever your anchor is, and pass the trap through the big loop.

No clips, snaps, or other crap you need to buy, and I can have a trap anchored faster than it takes me to compress the springs. You can also hook up several together if your anchor is a long way away. I can also use the cable anchors to anchor any size trap, and also as snare extensions, slide wire extensions, etc.

I just roll the anchors up after like a snare.

Make and end like on my Adjustable Length Sliders. Open it up to pass the trap through and close it back to gain length. see details on web site.
